QUESTION
race(
timer(2000).pipe(mapTo(1)),
timer(1000).pipe(mapTo(2)),
).toPromise().then(r => console.log(r))
...ANSWER
Answered 2021-Jun-06 at 05:41You are missing an important point about race
:
The observable to emit first is used
This means that if first emission of longActionObservable
occurs before the timer, then timer is not used, regardless of how long the "expand" observable takes to complete.
no toArray because I do not need result
Even though you don't need the result, toArray
actually makes this work as you wish because it will not allow any emissions until your "expand" observable completes. Instead of using toArray
, you could use reduce
instead:
QUESTION
Suppose I have a java.util.Collection that I want to loop over. Normally I'd do this:
...ANSWER
Answered 2021-Jun-01 at 17:26Your approach does not work. The correct approach is this:
- Unless you are a performance expert (which is hard to become), do not make assumptions about what kind of code performs well vs. performs poorly, and maintain skepticism when analysing profiler reports. This is not particularly useful advice (it boils down to: A profiler report may be lying to you!), but it is what it is. Effectively, either be a performance expert, or accept that there's not much you can do about it. Sucks, but, don't shoot the messenger.
- Write idiomatic java code. It is easiest to maintain and most likely to get optimized by hotspot.
- Reduction of algorithmic complexity is useful and should always be the first thing you check. To some extent, an optimization that reduces algorithmic complexity gets to ignore the first rule. You do not need to be particularly up to date on the vagaries of JVMTI or Flight Recorder and how profilers work to conclude that an algorithmic rewrite is worthwhile and is going to significantly improve performance.
- do not trust pithy rules of thumb, no matter how many people are saying it. Do not look for 'easy to apply patterns' like 'replace all foreach loops by appending an if-block that tests for empty first' - these are essentially never correct and usually reduce performance.
- Be aware that bad performance advice is rampant. You should never treat ubiquitous presence of some argument otherwise bereft of proof or research as "that makes it more likely to be true" as a general principle in life and logical reasoning (it is, after all, a logical fallacy!), but this counts double for performance!
Presumably, you're not going to trust the above maxims just because I'm telling you to trust them. I'll try to take you through some falsifiable reasoning to show you why the above maxims are correct.
In particular, this idea of checking for empty first seems extremely misguided.
Let's first translate the overly hyperbolical and therefore rather useless well-known maxim premature optimization is the root of all evil into something more tangible:
Do not make your code an ugly, caveat-ridden mess of weirdness because of an imagined performance issue.
Why can't I go by often-heard maxims?Do not go by "people" here. Because "people" are notorious for being utterly wrong on performance, time and time again. If you can find widespread, pithy and entirely bereft of proof or research statements that X is good or bad for performance, you can rest assured in the thought that this means absolutely nothing whatsoever. Your average joe twitter writter or whatnot is a clueless idiot in this regard. Proof, ample research, or credentials are an absolute requirement to take things seriously, preferably 2 or 3 of those. There are lists of well known performance falsehoods (commonly held beliefs about how to improve JVM performance that absolutely do not help whatsoever and often actually hurt), and if you then search for these falsehoods you can find entire hordes of folks who espouse it, thus proving that you just cannot trust anything based solely on the fact that you "keep hearing it".
Note also that for just about every imaginable line of java code, you can come up with 100+ plausible if somewhat exotic ideas on how to make the code less obvious but seemingly 'more performant'. Clearly then you can't apply all 100 variants to every line in the entire project, so the road you were planning on taking here ("I do not quite trust that profiler, I find it plausible escape analysis will fail to eliminate this iterator allocation, so, just to be safe I will add an if
that checks for empty first"), ends in a disaster where even the simplest task becomes a many-lined, seemingly excessively redundant soup. And performance will be worse on average, so it's a lose-lose scenario.
Here's a simple example to drive the point home, and you can watch those presentations by Doug for more of this sort of thing:
QUESTION
I have a workload running as an ECS service attached to a target group. Then I have an alarm monitoring that target group's instance count (HealthyHostCount). I'd like to implement blue/green deployments using 2 target groups, but it seems like because the alarm monitors a specific target group's value, it needs to be updated every deployment separately from the actual deployment.
This seems fragile and that there would be a better way to do this (e.g. after the deployment if we have a script that updates the alarm's target group, it could fail), but I can't see the better way. Is there an obviously easier solution?
...ANSWER
Answered 2021-May-15 at 23:15Instead of monitoring you have the desired number of healthy targets, monitor that you have no unhealthy ones. Your ECS service will take care of managing your desired count, plus you might want to scale the service so UnHealthyHostCount is the better metric to alarm on, I think anyway.
Create one alarm for each target group as below.
These won't trigger between normal ECS blue/green deployments, only if there is a registered target failing health-checks. You need to tune the health-check settings on the target group and HealthCheckGracePeriodSeconds setting for the ECS service accordingly.
QUESTION
I want to audit successful authorisations in a spring-boot 2.X application.
So I tried to start listening for AuthorizedEvent
but that event isn't published until AbstractSecurityInterceptor.publishAuthorizationSuccess
is set to true.
This application mostly uses @Secured
and @PreAuthorize
/@PostAuthorize
annotations so the interceptor I'm trying to listen to is MethodSecurityInterceptor
(It also gives me security roles being authorized against that FilterSecurityInterceptor
does not)
I don't see any way to configure MethodSecurityInterceptor
and enable event publishing other than through BeanPostProcessor
which feels fragile.
Is there a better way to enable MethodSecurityInterceptor.publishAuthorizationSuccess
than through BeanPostProcessor
?
ANSWER
Answered 2021-May-05 at 11:17Posted an issue in the spring-security github repo.
According to the reply there is no better way to configure MethodSecurityInterceptor
right now and they are making major changes in that part of the code so no point in improving anything right now.
So best way to configure MethodSecurityInterceptor
is through a BeanPostProcessor
like below:
QUESTION
the media query in my Grid-based CSS was not working all of a sudden (it was work fine weeks ago and I did not make any changes as for as I can recall). I tried different browsers (firefox, safari), disable cache on browser and verified correct CSS file downloaded by browser, but media query never worked. I tested below CSS and HTML file in http://www.cssdesk.com/, and again, Media Query was not working properly. I wasted almost half a day doing research and troubleshooting, now kind of give up (otherwise, my whole life would be wasted on the fragile CSS technology) and look forward to any help here. Thanks in advance.
My CSS file is as below:
...ANSWER
Answered 2021-May-01 at 11:56Your media query syntax is wrong.
Instead of:
@media screen only (min-width: 800 px) { ... }
Try:
@media only screen and (min-width: 800px) { ... }
What was wrong:
- Using
screen only
instead ofonly screen
. - Not using the
and
keyword to join media rules (screen
andmin-width
). - Using
800 px
instead of800px
QUESTION
I would like to style notifications in Vaadin Flow (19+), in Java, exactly as shown here in typescript, by assigning a theme and not setting the color of the elements (as shown in the java example). Apart the fact that setting the color is troublesome (foreground, background...) and fragile (e.g. switching to dark mode), the Java example shows setting a CSS color, I would expect to be allowed to use Lumo color variables (e.g. --lumo-success-color). Is this possible? Can anybody show an example?

method to define the variant you want to use:

QUESTION
Is there is a reliable way to determine if a given layered deployment has been successfully completed (=~ all edge modules in the deployment are running and configurations are applied) on a given edge device?
I'm wondering about a case where:
- a new layered deployment is created,
- the deployment is applied to a device (target condition matches),
- the edgeAgent marks the deployment as applied and starts downloading the images etc.,
- while downloading images, the device goes offline.
Is it possible now to determine that the deployment has not been completed on the edge device (other than looking at what modules are reported as running – but this is fragile, and deployments can contain more than just modules).
...ANSWER
Answered 2021-Apr-15 at 17:39Custom metrics for Automatic Device Management (ADM) deployments might help? https://docs.microsoft.com/azure/iot-hub/iot-hub-automatic-device-management#monitor-a-configuration
When you create a layered deployment for IoT Edge, you'll see a couple of pre-cooked custom metrics that you can use as a template.
QUESTION
I've got following setup: C#, ServiceStack, MariaDB, POCOs with objects and structs, JSON.
The main question is: how to use ServiceStack to store POCOs to MariaDB having complex types (objects and structs) blobbed as JSON and still have working de/serialization of the same POCOs? All of these single tasks are supported, but I had problems when all put together mainly because of structs.
... finally during writing this I found some solution and it may look like I answered my own question, but I still would like to know the answer from more skilled people, because the solution I found is a little bit complicated, I think. Details and two subquestions arise later in the context.
Sorry for the length and for possible misinformation caused by my limited knowledge.
Simple example. This is the final working one I ended with. At the beginning there were no SomeStruct.ToString()/Parse()
methods and no JsConfig
settings.
ANSWER
Answered 2021-Apr-02 at 09:19ServiceStack treats structs like a single scalar value type, just like most of the core BCL Value Types (e.g. TimeSpan
, DateTime
, etc). Overloading the Parse()
and ToString()
methods and Struct's Constructor
let you control the serialization/deserialization of custom structs.
Docs have been corrected. Structs use
Parse
whilst classes useParseJson/ParseJsv
If you want to serialize a models properties I'd suggest you use a class
instead as the behavior you're looking for is that of a POCO DTO.
If you want to have structs serailized as DTOs in your RDBMS an alternative you can try is to just use JSON.NET for the complex type serialization, e.g:
